WEAR PLATE FOR JOURNAL BOXES 0F LOCOMOTIVES AND ANALOGOUS CONSTRUCTIONS.

Application filed January 20, 1921.

To all whom it may concern.

Be it known that I, DANIEL F. GoNwARE, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Wear Plates for Journal Boxes of Locomotives and Analogous Constructions; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to wear plates for the journal boxes of locomotives and analogous constructions, and the device disclosed herein constitutes an improvement upon the device shown in U. S. Letters Patent No. 1,173,660, which was granted to me on February 29th, 1916. In the provision of constructions of the type under consideration it is particularly desirable that wear plates be provided which are readily removable from the journal box for replenishing with Babbitt metal or other anti-friction material. It is desirable that this removal be effected without jacking up 'or the loss of certainof the securing nuts. it

is necessary that means be provided to maintain a constant pressure on the nuts so that the same are not loosened by vibration and at the same time to, compensate for any slight wear which may occur between the relatively movable parts of the construction.

It is an object therefore of the present invention to provide an improved wear plate construction which will obviate the danger of the loss of the wear plate.

A further object of the invention is the provision of a construction of the type under consideration wherein certain of the portions are secured together by a resilient connection.

It is a further object of the invention to Serial No. $38,668.

The invention (in a preferred form) is shown on the drawings and hereinafter more fully described.

Asshown on the drawings:

In the preferred embodiment of this invention illustrated herein, the reference numeral 1 represents an engine or locomotive wheel secured to or mounted on the end of an axle 2 which is engaged through a journal box 3 provided with an improved wear plate :1: removably interposed between the hub 5 of the wheel 1 and the journal box. The ournal box 3 is fitted with the usual brass 6 which rests upon the axle and which has a lubricant cellar 7 of the usual construction. This lubricant cellar 7 is commonly secured between the downward extensions 8 of the journal box, and, as shown in Figure 8, the downward extensions 8 are provided at their lower ends with inner longitudinal guides 9 on which said lubricant cellar 7 is removably mounted. As shown in Figure 1, the cellar 7 is detachably secured to the journal box by means of a transverse bolt 10 which extends box 7. The general form of the improved wear plate or liner is shown in Flgures 3 and 5. The device comprises a flat bifurcated anchor plate 12 which is adapted to slip over the axle and which is adapted to afford a casing for the outer end of the journal box,

and a correspondingly recessed wear member 13 which is removably secured in a recess or socket 14 in the outer face of the plate 12. The outer diameter of the wear member 13 is greater than the diameter of the hub 5 and said wear member 13 is preferabl composed of Babbitt metal or other suitab e antifrictional material which may be readily renewed when necessary. The base of the plate 12 is provided with a circular recess which is filled by the wear member 13, as shown in Figures 1 and 3. The recess in the plate provides an outwardly projecting annular lip 15 in which the recess 14 is out. The recessed portion of the plate 12 is provided with undercut circular depressions or small sockets which receive anchoring portions 16 of Babbitt metal as is shown in Figures 1 and 3. The Babbitt metal is poured into the socket provided for it in the base of the wear plate and the metal becomes anchored in the annular groove 14 and in the undercut sockets which receive the anchoring portion 16 of Babbitt metal. The inner ends of said portion 16 are enlarged on account of the fact that metal of the plate 12 is undercut at'the recesses so that the Babbitt metal becomes securely anchored in. the socket. Thus the body of the wear member is firmly anchored to the body of the wear plate or holder 12. The wear plate as a whole comprising the plate 12 and the wear member 13 is recessed centrally from the lower edge upwardly as indicated at 17, the re ess terminating in an upper wall 18 which. bears upon the projecting end of the brass 6. The plate 12 is provided at its lateral edges with flanges 19 which are turned away from the hub of the wheel and said flanges 19 embrace the lateral fla-nges 20 with which the journal box is provided at its outer end, the flanges 19 being equipped on their inner faces with integral keys 21 which engage grooves 22 with which the flanges 21 are provided in their vertical edge portion. Thus it is possible to remove the wear plates by a vertical movement due to the guiding action of said flanges and grooves. The upper end of the plate 12 is provided with an mturned flange 23 which is equipped with a downturn'ed flange 24 engaging an upstanding flange 25 with which the upper portion of the outer end of the journal box is provided. The upper portion of the wear plate is provided with a recess or chamber 26 which is adapted to contain lubricant. From the chamber 26 are led oil ducts 27 which are adapted to discharge oil between the base of the wear plate and the hub of the wheel.

As has been previously described, the plate 12 has downward extensions 28 which pass outside the axle 2 and these extensions have formed integrally with theirouter portions at their lower ends lugs 29, to which are secured downwardly extending threaded bolts 30. Said bolts 30 are preferably threaded throughout their length and have their upper ends screwed into the threaded socket in the lugs 29, being secured therein by pins 31. The bolts 30 extend through recessed lugs 32 carried by and forming a part of the journal box, and the recesses in the lugs 32, through which the bolts 30 extend, are enlarged as indicated at 33 to provide sockets or bearings for coiled springs 34 whose upper ends bear against the upper walls of the enlarged opening and whose lower ends bear against nuts 35 screwed onto the lower end of the bolts 30. Saidnuts 35 are preferably tightened so as to bear against the lower ends of the lugs 32 and the springs 34 are accordingly placed under relatively heavy compression by the turning of the nuts 35 up against the bottom of the lugs. Thus in case of wear or in case the nuts should work loose the wear plate will be held in its proper position under the heavy force transmitted through the springs to the lower portion of the journal box. The lugs 32 are shown as formed separately from the journal box and at tached to the outer corners thereof. This arrangement is necessary where the improved wear plate is to be used in connection with existing constructions which are not provided with such lugs. Obviously, however, the journal box may be constructed with integral lugs if desired. In the illustration given the bearings or lugs 32 are provided with attaching shanks 36, as clearly shown in Figures 3 and 6. Said shanks 36 have flanges 37 thereon which fit beneath the corner portions of the journal box and have vertical flanges 38 which embrace the sides of the journal box. Said flanges 38 are connected with the walls of the journal box by means of bolts 39. It will be apparent that the recessed portion of the U-shaped wear plate 4 bears upon the upper portion of the journal box in a manner shown in Figure 1, the spring 34 acting to hold the wear plate firmly in position and to prevent vertical oscillation and also tending to hold the flanges 37 of the securing lugs firmly against the bottom wall of the journal box. In this manner the danger of shearing of the bolts 27 as a result of -vibration is minimized.

The operation is as follows: Practical use of the improved device of this invention has demonstrated the fact till re -eases that the improved form of connection between the wear plate and the journal box described herein will serve to prevent the wear plate from working loose and ultimately becoming lost. It will be noted that the outer base of the wear member 13 at fords a wear surface which contacts with the inner vertical base of the hub 5 of the wheel. When the wear member becomes worn the plate 6 may be removed from the axle without dismemberment of the locomotive or tender and it is not necessary to drop the axle out of its bearing in order to enable a new wearing surface to be applied to the outer end of a journal box. In the construction of this invention the wear plate may be removed at will and the worn out wearing surface may be removed and a new surface provided. Thus the same wear plate ma be used many times by simply rebabbittmg or renewing the anti-friction material in the wear member 13 when the same becomes worn. The wear member may be removed conveniently by heating the holder plate so as to melt the babbit-t there in and by means of suitable moulding apparatus melted babbitt or other suitable material may be poured into the recess in the base of the plate 12, suitable provision being made in the moulding apparatus for providing a proper wear surface at the exposed side of the Babbitt metal. The Babbitt metal, of course, becomes anchored firmly in the socket 16 and the groove 14: in the wear plate.

It will be apparent from the foregoing specification that this invention makes practical use of wear plates of the type under consideration, facilitating the work of keeping the locomotive in proper running order at a minimum expense, since the discard of worn-out parts is greatly diminished.

l am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:
